REYNOLDS, OF NEW YORK, ,N2 Y., ASSIGNORS TO mg1Gn;mNOLDSYINCLLOENEW YORK, N. Y., A CORPORATION OF NEW YORK RIBBON BURNER Appneauen mea september 22, 152s., serial No. 307,634.

This invention relates to-gas burners, particularly to what is known as ribbon burners 'used in large furnaces, a's, for instance, those used in bakeries, the object being to provide an improved burner structure which will present a desired flame, and which will not become extinguished readily.

Another object of the invention is to provide an improved burner, wherein the jet or 'm opening for'the gas is provided with means which will prevent the extinguishing of the flame by drafts and the like, even when the suppl of gas is small.

A rther object, more specifically, is .to

f1-5 provide a burner wherein a plurality of corrugated distributing members are presented and arranged so as to dividethe gas into small jets over a given area. n

In the accompanying drawingy Figure l is a longitudinal vertical sectional view through a burner disclosing an embodiment of the invention,

Figure 2 is an enlarged fragmentary view similar to part of the burner shown in Figi' 25 ure 1, said View illustrating the diagonal arrangement of the distributing plates,

Figure 3 is a top plan view of the structure shown in Figure 2,

Figure 4 is an enlargedfragmentary secl 3o tional view through Figure 1 on line 4 4.

Referring to the accompanying drawing by numeral, 1 indicates the burner as a whole. Burner 1 is provided with a pipe or gas-distributing tube 2 having a slot 3 therein extending from near one end tonear the opposite end. This slot is very narrow and is the outlet for the gas. This slot may be ifteen feet long, or if desired, may be very short. Where it is long, it is difficult to distribute the gas properly and at the same time prevent the flame from going out when the gas has been turned down somewhat. To obviate these objections and others,the slot 3 is filled y with a number of gas-distributing plates 4.

These plates are referably identical in structure and are pre erably sutliciently numerous to snugl fill the slot 3, as shown in Figures 3 and 4. llach of these plates is corrugated for its full length, the corrugations 5 extending diagonally from one edge to the other, thus Ucause the llame to be maintained as long as any gas is furnished. As shown in Figure 3 only threeplates 4 have been used. If desired, a large number could be used Without departing from the spirit of the invention. In fact, a square or round burneropening could be provided and these plates used therein. 'However,'when used in the burner disi closed, the plates are snugly arranged in the slot 3 and several holes are drilled therethrough and also through the tube 2, as shown in Figure 4. The rivet 8 extends through each group of holes and is preferably welded at the ends 9 and 1Q. In this way, the plates 4 are held in position and alsothe slot 3 is prevented from spreading during the use 0f the burner. The plates 4 are preferably made from a desired grade of metal and are preferably ver thin, usually from one-fiftieth to one hun redth part of an inch thick. It will, of course, be'evident that the plates could be of substantially 'any desired thickness and the grooves of any arc,'but preferably the "grooves are very small and the angle of the ridges 5 is not great, but sulicient to make the inlet opening of a groove offset slightly from the outlet opening.

' What is claimed is 1 1. In a ribbon burner, a tubular member having a slot acting as the burner tip, and a filling structure arranged in said slot for dividing the gas escaping therefrom, said filling structure consisting of not less than two strips of corrugated metal in contact, with the corrugations at an angle other than to the edges.

2. In a burner provided with an opening through which the gas is adapted to escape when burning and a plurality of corrugated plates arranged in said opening, and adapted to expand and contract with'the material in which the opening is f ormed and at the same time continually present small openings, each of said lates having the corrugations at an angle ot er than a 90 angle from the edges. 3. In a burner .a plurality of plates at the discharge opening of the burner, said plates being formed with grooves on Aa bias and positioned so as to produce a large number lo of independent openings closely juxtaposed, each of said openings consisting of the ends of not -more than two of said grooves.v

4. In a burner 'a plurality of contacting gas dividing plates, each plate presenting a ribbon formation corrugated throughout with the corrugations extending from one longitudinal edge to the' other longitudinal edge at an angle other than a right angle.

5. A gas burner having in combination, a burner tube, said tube being formed longitudinally in one side thereof with an elongated slot2 a corrugated strip in said slot and orming Jet passages therewith, said strip extending -into said tube, and a plurality of spaced tie members extending laterally through said tube and said strip to hold said stri 1n position and the sides of said slot against said strip.

6. A gas burner having in combination, a burner tube adapted to receive gas, said tube being formed longitudinally in one side. thereof with an enlongated slot, means in said slot defining a plurality of jet passages along said slot, sald means extending into said tube,

and a pluralit of spaced tie members extending latera y through said tube and said means to hold said means in osition and the sides of said slot against sai means.

7. A as burner having, in combination, a hollow urner member adapted to receive gas, said member being formed with an elongated slot, corrugated-means in said slot defining a plurality of jet passages therewith, said means extending laterally into said member, and a plurality of spaced tie members extending later-allythroughv said member and said means to hold said means in position and to hold the sides of said slot against said means.

8. A ribbon burner, comprising means forming a slot throu h which gas is adapted, to escape when the urner is 1n use, a plurality of plates maintained in said slot, and rivets extending through said plates for holding the plates in position and or` preventing lateral enlargement of said slot due to expansion of the material in which the slot is formed, each of said plates being corrugated with the corrugations extending at an angle other than a right angle to the edge of the plate, the entire surface of each plate being corrugated whereby small openings are provided in the slot through which the gas is adapted to pass.

66 9. In a gas burner, a gas distributing jet comprisin a lurality of Vplates arranged in a slot, eac o said plates being corrugated throughout, their respective corrugatons being' at an angle other than a right angle to the edge .of the plate and extendlng from one longltudmal edge to the o posite longitudinal edge, the adjacent p ates being posiionedl'stoeghatltihleecorrugatins on the respec- 1ve p a w1 o osite y inclined.
